Anyone had experience with this replacement PCM?
 
Car is a 2008 CX-9 3.7L AWD

The website seems to have mixed reviews, so I'm not sure whether to go with this. Anyone bought from this company before? Bonus question, is it even worth it to replace the PCM? Engine light has been on for a year with the code 'corrupt/non exist programming PCM', code P1639. But it's been a year and nothing's happened really. Should I even bother?

I assume you've tried clearing the code? Do you have any other PCM codes? Is it affecting the driveability of the vehicle?

Yes, no, and no. Car has been driving fine for around a year.

If your long term fuel usage hasn't changed, I wouldn't bother fixing it.
